4 Claims. (Cl. 5*??23) This invention relates to splicing. rigs. The general object of the invention is to provide a portable, self-contained splicing apparatus which includes all the necessary mechanisms in operator.

A more speci provide an improved s mit the ready splicing fic object of the invention is to plicing rig which will perof the end of a cable for for the purthe purpose of Joining two cables or pose of making a loop in the end of a cable.

In splicing cables, which are made of a number of tightly twisted strands of wire, it is necesf sary to untwist a portion to form gaps in the cable to permit untwisted end portions ofthe cable to be run through the gaps. 'Thereafter the strands are twisted back to their norma osition and the splice is made.l n p It is one of the specific objects of my invene tion to provide a novel member for holding both the ends of the cable which are being worked upon and the remainder of the cable.

A further object of the invention 1s to provide a cable splicing rig including a novel suporting arm for the cable.

p A further object of the invention is to piovi'de a novel means for clamping a cable on a splicing rig. Another object of the inve a novel mounting for the clamping me cable splicing rig. t v

A further object of the invention 'is toprovde a novel standard for a cable splicing rig..

Other objects and advantages or the invention will be apparent from the following description taken in connection with the accompanying drawings, wherein: c

unit including a support ntion is tov provide' Referring to the drawings by reference characters, I have shown my invention as embodied in a cable splicing rig which is indicated generally as at IB. As shown, the rig includes a base member I I which has pads I2 secured thereto, allowing the apparatus to be supported. An upright 'member I3 is supported by the base and extends at right angles thereto. The upright includes a pad I4 which serves to support the rig. The apparatus may be supported in a vertical position as shown in Fig. l with the pads ll2 resting upon a base and the pad I4 secured upon a support or the apparatus may be mounted with the member I3 horizontales the worker may prefer. i

Pivotally mounted on the upright I3., as at I5, I show a gripping vise arm i 6. The gripping vise arm has a vise jaw I8 which is mounted to rotate on a threaded member I9 which passes through a nut 29 and is operated by a hand wheel 2i. A bracket 22, welded as at 23 to the arm I6, supports the nut 2l).

-When a cable is placed between the jaws I1 and I8 and the wheel ZID is rotated, the member I9 will thread through the nut 2!) and will advance the jaw i8 towards the jaw I'I to hold the cable in position.

Iny order to raise the arm IB and increase the tension on the cable after thelatter has been engaged by a lower clamping means (to be later described), I provide an adjusting member 24 which has an operating whee1'25 thereon and which is reversely threaded at each end to threadedly receive eye members 26 and 21 which are pivoted to brackets 28 and 29 respectively. The bracket 28 is mounted on the arm I6 and the bracket 29 is mounted on the upright I3.

The base member l l supports a table which is xed thereon. On the table 35 I arrange a sup-v portmember 36 through which a shaft 3l eX- tends. The lower end of the'shaft 31 includes a bearing 38 which engagesball bearings 39 `arranged in a raceway 40 on-the support member 36. The shaft 31 includes a head 4I and a nut 42 for holding the parts assembled. The shaft 3l includes an oil slot 43 leading to the ball bearings 39. r

Arranged about the shaft I show a ball retainer 44 which supports ball bearings 45. The balls 45 engage the support member 36 and also engage a plate 4B from which a dust guard 41 depends. A lubricating fitting 43 serves to supply lubricant to the balls 45. The plate 46 is secured as by welding at 49 to a plate 5|] and both the plates 46 and the plate 50 are secured to the lower edges 5I of a channel member or vise base 52 by Welding as at 53 (Fig. 3).

The construction is such that the vise base 52 is rotatably supported on the table 35. To hold the vise base 52 in position the base is provided with a tube 54 to which a rod 55 extends. The rod 55 enters any one of a plurality of holes 56 in the table 35 to hold the parts assembled.

Mounted on the base 52 I show a vise support which consistsiof an upright tube-B5 which is cut away as at lllandhas a rear Wall 6l. The Wall El has a slot 62 through which the bent end B3 of the rod 55 extends. The wall 6l includes a shelf 55 which is apertured as at 65 to receive splicing tools 66. The shelf also includes a tube 61 which is welded as at B8 to the shelf and which slidably receives a rod 69 which may be withdrawn to serve as a handle by means of which the vise support may be rotated.

Mounted upon the tube 60 I show a splicing vise, indicated generally as at 10. The vise includes a base 1I having jawsy 12 and 13 thereon.

The jaws 12 and 13 are mounted to rotate relative to threaded members 14 and 15, respectively. The threaded member 15 includes an operating bar 16, by means of Which the jaw 13 may be moved towards the jaw 12 to hold the parts assembled during the splicing operation.

The base 1| includes an internally threaded portion B0 which receives a threaded member 8|. This threaded member 8l has a slide member 82 thereon. The member 82 slides along the base 1| when rotated by an arm 83 and moves along ways 84. Y

In using my improved splicing rig, the operator opens the jaws I8 and 13, then runs a cable C through the jaw I8 and turns the wheel 2| to clamp the cable in place. The cable is brought back inside the jaw 13 and the operating bar 16 is then rotated to clamp the free end of the cable against the adjacent portion so that a loop L is formed. The slide member 82 serves to determine the size of the loop L. The operating wheel may then be rotated to shift the arm i6 to make the cable taut.. The rod 69 is then moved to shift the movable jaw, a vise stand, means to pivotally support said vise stand on said base member for rotation, a vise support on said vise stand, a splicing vise on said vise support, said splicing vise including a body having a fixed jaw and a movable jaw thereon, and means to move the splicing vise movable jaw.

2. A cable splicing rig including a base member, an upright mounted on said base member, a grippingv vise arm pivoted onsaid` upright and extendingoutwardly therefrom, means to support said arm in adjusted position relative to said upright, a xed jaw member on said arm, a movable jaw member on said arm, means for operating the movable jaw, a vise stand, means to support said viseV stand for rotation on said base member, means to hold said vise stand in adjusted position, a vise support on said vise stand, a splicing vise on said vise support, said splicing vise including a body having a fixed jaw and a movable jaw thereon, means to move the splicing vise movable jaw, and a cable loop engaging member shiftably mounted on the vise support adjacent to said splicing vise.

3. A cable splicing rig including a base member, an upright mounted on said base member. and extending at right angles thereto, a gripping vise arm pivoted at one end on said upright and extending outwardly therefrom, means to support said arm in adjusted angular position relative to said upright, a fixed jaw member on said arm, a

movable jawmember on said arm, means at the free end of the arm for operating the movable jaw, a table on said base member, a vise stand, means to mount said vise stand on said table for rotation about an axis parallel to said upright, means to hold said vise stand in adjusted angular position relative to said table, a vise support on the base 1| and unwind the cable so that the strands 85 of the free end may be inserted between the strands of the body portion of the cable to secure the splice. The necessary tools 66 may be removed from the shelf 64 for this purpose. The cable may then be twisted by swinging the rod 69 so that the cable assumes a normal position and thereafter the various vises are released and the cable removed. t

From the foregoing description it Will be apparent that I have invented a novel cable splicing apparatus which may be economically manufactured and which is highly efficient for its intended purpose.

Having thus described my invention, I claim:

1. A cable splicing rig including a base member. an upright mounted on said base member a rgripping vise arm pivoted on said upright and extending outwardly therefrom, means to support said arm in adjusted position relative to said upright, a fixed jaw member on said arm, a movable jaw member on said arm, means for operating said vise stand, a tube on said vise support, an operating rod slidable in said tube, a splicing vise on said vise support, said splicing vise including a body having a xed jaW and a movable jaw thereon, means to move the splicing vise movable jaw, and a cable loop engaging member shiftably mounted on the vise support adjacent to said splicing vise.
